Instructions
Go to the 100-yard marker for the gun range.
Hold up the gun in a firing position. Verify that the safety is on and keep your finger away from the trigger.
Measure the distance from the barrel of the gun to the ground with a tape measure. Make a note of the measurement.
Fire the gun at the target. Examine the target and note the location of the bullet hole.
Move back to the 200-yard marker. Hold the gun in firing position at the same height you measured in Step 3.
Fire the gun at the target. Examine the target and make a note of the bullet hole.
Measure from the ground to the first hole and make a note of the measurement. Measure to the second hole and note the measurement.
Subtract the second measurement from the first to determine height drop from 100 yards to 200 yards.
